Abstract

Introduction The standard chemotherapy for squamous NSCLC (sqNSCLC) includes platinum plus gemcitabine. Sintilimab, an anti-programmed cell death protein 1 antibody, plus platinum and gemcitabine (GP) has revealed encouraging efficacy as first-line therapy for sqNSCLC in a phase 1b study. We conducted a randomized, double-blind, phase 3 study to further compare the efficacy and safety of sintilimab with placebo, both in combination with GP.Methods ORIENT-12, a randomized, double-blind, phase 3 study, was conducted at 42 centers in the People's Republic of China (ClinicalTrials.gov, number NCT03629925). Patients with locally advanced or metastatic sqNSCLC and without EGFR-sensitive mutations or ALK rearrangements were enrolled in the study. The stratification factors included clinical stage, choice of platinum, and programmed death-ligand 1 tumor proportion score. The patients, investigators, research staff, and sponsor team were masked to treatment assignment. Eligible patients were randomized 1:1, using an integrated web-response system, to receive sintilimab 200 mg or placebo plus GP every 3 weeks for four or six cycles, followed by sintilimab or placebo as maintenance therapy until disease progression or 2 years. The primary end point was progression-free survival (PFS), assessed by an independent radiographic review committee.Results Between September 25, 2018 and July 26, 2019, a total of 543 patients were screened, of whom 357 patients were randomized to the sintilimab-GP group (n = 179) and the placebo-GP group (n = 178). After a median follow-up period of 12.9 months, sintilimab-GP continued to reveal a meaningful improvement in PFS than placebo-GP (hazard ratio = 0.536 [95% confidence interval: 0.422-0.681], p < 0.00001). Treatment-emergent adverse events of grade 3 or worse occurred in 86.6% patients in the sintilimab-GP group and in 83.1% in the placebo-GP group. The incidence of treatment-emergent adverse event leading to death was 4.5% and 6.7% in the two treatment groups, respectively.Conclusions Regarding PFS, sintilimab plus GP reveals clinical benefit than GP alone as first-line therapy in patients with locally advanced or metastatic sqNSCLC. The toxicity was acceptable, and no new unexpected safety signals were observed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
